Be it known that I, THOMAS JJKERN, a citizen oi the United States,residin 'at Antioch in. the county of Lake and 'etete of Illinois, haveinvented certain new and useful Improvements in Stroppers for RomeoElades, of which the following is a; 'specifico- This invention relatesto improrements in devices or machines for stropping or shar aeningrazor blades, and it consists in certain peculiarities of theconstruction, novel orrangement operation of the various parts thereofwill be herci oeiter more fully set forth and s iecifieelly rleime-o.

The principal object oftile invention is t lorovide st ier or sharpenerfor re blades, pert My detachable blades, such as are used 11 manysafety razors, which shall be compost in form, simple and iueze pensivein construction, strong, durable, and eilicient in opera lion; Anotherobj of the intention is to provide a stropper of the abovementionedgencrel character, wherein the arrangement and construction ofthe parts thereof is such as to eriable either sin gle or double edgedblades, or the blades of different makes of razors, to he stropped withequei feoiiity, proper provision being made for clamping or holdingblades of difi'erent types-sod for swinging the edge 01 edges or theblades into Without danger of cutting the some as the movement of theletter is reversed or drawn longitudinally througli'tlie frame oi thedevice in the operation of stropping. Various other objects andadvantages of the invention will be disclosed in the subioined description and explanation;

in the accompanying drawing which serves to illustrate an embodiment ofthe invention, 5 V Figure 1 is a face View of the device showing thefront run oi part of. the strep removed.

On each of these rods a rotary sleeve 1.4by pr ference mounted, but .i. desire it to he or f rsiood that saidslum may be omitted, in "hich easel at least the rod 153 may be rot Lnalod in the sid l0 and ii At its upper end -t frame a loop or hail 15of.

Traiisverseiy izrimled about midibetween the tie rod 12 or sleeve 14: thereon and the tierods 1-3 orsleeves le thereon is the oody'plete 16 o A holder, which plate is bypref" rice 0 fiat ietal end has at one of its ends stuii ieit" 17extended through a suiiohlei 2e ing; lil We the side piece 10 ofthcframe and at s other end an extension 18 on which is mounted the neck 19of a knob or handle 20 which knob or handle isprovided with a conicalshaped cavity 21 connnuni nting .With an opening 22 extended centrallythrough the neck 19 of the knob. The inner end of the neck 19 isprovided with an annular flange the knob or handle in position on theplate 1.6, yet so that the said knob or handle may be turnedindependently thereof. T he body plate 16 is provided with. one or morestuds 26 which are for the purpose of engaging correspondingly spacedopenings in the razor blades 27 of the Gillette type so as to moresecurely hold said blades in position thereon. Secured to the end of thebody plate 16 opposite the handle 20 by means of a hinge 28 is a curvedresilient clamping member 29 which is provided with openings 30 toregister with and receive the studs 96 on the body plate, that is, whenblades of the Gillette type, or those having openings, therein betweentheir ends are being stropped.- The opposite end of the clamping memberfrom the hinge 28 is provided with a projection 31 which is adapted toen ter the inclosure formed by the flange 23 on theneck 19 of the knobor handle 20, through the cut-away portion 2% of said flange which willengage the projection 31 and hold the member 29 in its operativeorclosed position, it being understood that the neck 19 of the knob orhandle 20 is journalcd in a, suitable opening in the side 11 of theframe of the device. That end of the body plate 16 adjacent to the hinge28 is provided at one of its sides with a laterally extended arm 32which has an outward projection 33 extended into the slot 34- formed inthe inner portion of an arm 3.? rigidly fixed to one end of the sleeveor rock-shaft 14 over which the strep 36 passes. The same end of theblade holder consisting of the body plate 16 and the clamping memher 29is provided with a pair of projections 37 which are located on oppositesides of the stub shaft 17 oi the body plate and extend into segmentalslots 38 forum-d in the side piece '10 on each side of said, shalt. Bythis arrangement it is evident that through the com nections 1-3" 0-5and projections 37 with the ends of the slots 38' the body plate 16 oithe blade holder will be restricted in its moveim-nl's, yet may be"roclfiwl by alternately pulling on the runs of the strop :36. which abefore stated passes over the sleeve or ro k-shaft ll, and as 3:7, withthe sleeve 01' roclcsbal't l-l and the engagement of the shown-in Fig. 2of the drawingpasses between the tie rods 13 and rollers ldthereon,

- when the latter are used.

In Fig. 41- of the drawing a modification ithe construction of the bladeholder is shown which holder is of similar construe-- tion to that abovedescribed, except that a plate or piece, of cushioning material 39having openings 4:0 for the reception of the studs 26 on the body plate16 is placed be tween the said plate and the clamping member 29. By thisarrangement it will be understood that if it is. desired to strep arazor blade ll of the Gem or other type not having openings therein thiscan be done by simply placing the blade between the cushion. or. piece39 and the clamp 29 and fastening the latter in position by turning theknob 20 as in the other construction, after which it is obvious that byalternately drawing on the ends of the strep 36 the edge of the bladewill be caused to contact alternately Wit-l1 the runs of the strop andbe sharpened thereby. The same operation is performed in stroppingdouble edged blades or those of the Gillette type as shown in Figs. 2 or3 of the drawing.

Having thus fully described my inven tion, What I claim as new anddesire to secure by Letters latent is- '1. A stropper for razor bladesconsisting of a frame having parallel sides, one of said sides having apair of spaced apart segmental slots, a rock shaft transverselyjournaled in the upper portion of the frame, a blade holder consistingof a body plate and a clamping plate hinged at one of its ends to oneend of the body plate, said body plate jour'naled on the frame near saidshaft in parallelism therewith, one of the journals of said body platebeing located be tween said slots of the frame, said body plate having apair of projections extended into said slots and provided at itsopposite end With an extension divided at its outer portion, aslottedarm rigidly mounted on the rock shaft, a projection extended fromthe blade holder into the slot of said arm, a knob rotatably mounted onsaid extension and having in its outer portion a conical shaped recessto receive and engage the prongs of said extensilm, said knob extendedthrough an opening in the frame and having at its inner end acircumferential flange provided with a recess therein, said clampingplate having at its end opposite its hinged portion a projection toenter said recess and engage the flange of said knob, and a strepextended over the rock shaft to operate the same.

2. A stropper ,t'or razor blades including in combination, a frame, ablade holder journaled in said frame and consisting of a body platehaving at one of its ends an ex tension provided at its outer portion, a
